CFD simulation of the wind over a terrain
 

Dear all,

I have to perform the simulation of the wind over the terrain of a certain area. I start from a DTED map.

I would like to know which are the steps I have to do in order to get some good results.

1. how can I get an OpenFOAM-compatible mesh, from a DTED?
2. which is the best turbulence model in OpenFOAM to perform a wind simulation?
3. how can I build a suitable domain "around" the DTED map I download?

Thanks a lot,

Samuele
